HAND-STAMP.

Specification of Letters Patent No. 16,731, dated March 3, 1857.

To all whom 'it 'may concern:

Be it known that I, HORACE HoL'r, of IVinchester, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Hand- Stamps, of which the following is a full,clear, and exact description, reference being had to t-he accompanyingdrawings, making part of this specification, in which- C, is thepedestal or base from which rises the standard D supporting the movingparts of the apparatus; to the upper part of this standard are attachedthe lugs E between which plays the handle F pivoted at a and having thearm G and toe I) (seen dotted in the drawing). To one side of thestandard is attached the sleeve H in which plays the rod I to the bottomof which is attached the die or stamp K; this rod is held up in theposition shown in the drawing by a spiral spring L the end of the arm Gresting on the top of the rod I. The inking roll M is hung in the arms Nwhich are pivoted at c one one each side of the sleeve H; the axle ofthe roll plays up and down in slits d in the lower end of the arm Nbeing held up to its work by the springs f there being one at each endof the roll. To each of the arms N are pivoted at g, near the upper end,the short arms P which are connected together by the cross piece L fromwhich projects between the lugs E the dog z' against the end of whichrests the toe the spring m which is attached at fn, to each side of thestandard D and which presses against the cross piece L serving to keepthe ink roll up in the position shown in the drawing when not forcedtherefrom by the movement of the handle F.

R is the platen on which the article to be stamped is placed; it iscovered with cloth in the ordinary manner.

Operation: The handle F being moved in the direction of the arrow untilits end. reaches A the toe o pressing against the dog z' forces the rollM in the direction of the arrow A beneath t-he die K inking the face ofit, the springs f causing the roll to accommodate itself to the surfaceof the die. The handle F is now moved in the opposite direction toward Bthe point of the arm G pressing upon the rod I forces the die K downvertically upon the platen R or upon the article to be stamped as showndotted at B. In moving the handle from A toward B as it regains itsvertical position the spring m throws the roll M back into its originalposition before the rod I commences its vertical descent. When theimpression has been made and the hand of the operator is removed fromthe handle the spring L raises the rod I into its original position thetop of the die K resting against the bottom of the sleeve H.

I do not claim operating the platen or stem and the inking roll by asingle operation of the hand but What I do claim as my invention anddesire to secure by Letters Patent is- The combination of a detachedlever with its toe pieces for inking and taking the impression, whensaid inking and impressing devices are returned to their places bysprings as set forth.
